Product Overview

The Eye Slip Hook is a practical lifting component designed for use with chain slings, rigging assemblies and industrial material handling equipment.

Its eye connection allows the hook to be integrated with compatible lifting chains or other approved rigging components. The hook bowl provides a seating point for the connected chain, sling or lifting accessory.

A safety latch can be fitted to help prevent accidental disengagement when the hook is properly positioned during lifting.

The hook can be supplied in different sizes and load capacities according to the customer's requirements. Material, forging process, heat treatment, surface finish, WLL and testing can be specified according to the intended application and applicable lifting standard.

Important: The actual Working Load Limit (WLL) depends on the specific hook model, material, dimensions and complete lifting configuration. Buyers should refer to the product marking and technical documentation rather than assuming a capacity from the hook size alone.

Key Features

1. Forged Steel Construction

The eye slip hook can be manufactured using suitable high-strength steel and a controlled forging process.

The material and heat treatment are selected according to the required mechanical properties and lifting application.

Typical benefits include:

• High mechanical strength
• Robust load-bearing structure
• Good durability
• Suitable toughness
• Reliable connection for compatible rigging systems

2. Eye Slip Design

The eye at the top of the hook provides a connection point for compatible chain sling components.

The eye dimensions should be matched to:

• Chain diameter
• Master link
• Connecting link
• Sling configuration
• Required WLL

Components should not be selected only because they physically fit together.

3. Safety Latch

The hook can be equipped with a safety latch across the hook opening.

The latch helps retain the connected chain or sling component and reduce accidental disengagement.

The load must always be carried by the hook bowl, not by the safety latch.

4. Suitable for Chain Sling Assemblies

Eye slip hooks are commonly used as end components in chain sling systems.

They can be incorporated into:

• Single-leg chain slings
• Two-leg chain slings
• Three-leg chain slings
• Four-leg chain slings
• Adjustable chain sling assemblies

The final assembly WLL should be determined according to the complete sling configuration.

5. Multiple Sizes Available

Different hook sizes can be supplied for different chain diameters and lifting capacities.

Typical customized parameters include:

• Hook size
• Chain diameter
• WLL
• Hook opening
• Eye dimensions
• Overall dimensions
• Surface finish

Technical Specifications

Main Components

Forged Hook Body

The main load-bearing part of the hook.

Eye

The upper connection section used to attach the hook to a compatible chain or rigging component.

Hook Bowl

The curved section where the load-bearing component should be properly seated.

Safety Latch

A retaining mechanism that helps prevent accidental opening of the hook.

Latch Pin

Connects the safety latch to the hook body.

Working Load Limit

The Working Load Limit (WLL) is the maximum rated load for the hook under specified lifting conditions.

The actual WLL depends on:

• Material grade
• Hook dimensions
• Hook geometry
• Heat treatment
• Manufacturing process
• Chain diameter
• Safety factor
• Applicable standard
• Complete sling configuration

For example, when an eye slip hook is used as part of a multi-leg chain sling, the overall sling capacity is also affected by the number of legs and sling angle.

Therefore, the hook WLL and complete chain sling WLL should be verified separately.

Eye Slip Hook vs. Grab Hook

The correct hook should be selected according to the lifting system and chain configuration.

Product Advantages

Applications

Chain Sling

The eye slip hook can be installed at the end of a Grade 80 or other appropriately specified chain sling.

Crane Lifting

Suitable for compatible crane and hoisting applications when the hook is correctly rated.

Industrial Material Handling

Used for lifting machinery, steel components, fabricated structures and industrial equipment.

Construction

Applicable to construction material handling and lifting operations with properly rated rigging equipment.

Factory & Warehouse Operations

Can be used for moving heavy components and equipment in industrial facilities.

Heavy Equipment Handling

Suitable for loading, unloading and positioning equipment when the complete lifting assembly meets the required capacity.

How to Select the Right Eye Slip Hook

1. Determine the Required WLL

Calculate the weight of the load and select a hook with an appropriate rated WLL.

Do not determine capacity from hook appearance or dimensions alone.

2. Match the Chain Diameter

The hook eye should be compatible with the selected chain and connecting components.

For Grade 80 chain slings, the hook should be matched to the specified chain grade and diameter.

3. Check Hook Opening

The opening should provide enough space for the intended connecting component while allowing the load to sit correctly in the bowl.

4. Check the Lifting Configuration

Consider whether the hook will be used in:

• Single-leg lifting
• Two-leg lifting
• Three-leg lifting
• Four-leg lifting

For multi-leg slings, the sling angle must also be considered.

5. Confirm the Safety Latch

Check that the latch operates correctly and is not damaged or deformed.

Manufacturing Process

1. Raw Material Inspection

Steel material is inspected according to the specified material requirements.

2. Heating

The steel is heated to the required forging temperature.

3. Drop Forging

The heated material is forged into the hook body using controlled dies.

4. Trimming

Excess forging material is removed.

5. Heat Treatment

Controlled heat treatment is carried out according to the material and required mechanical properties.

6. Machining

The eye, latch connection and other specified areas are machined.

7. Safety Latch Assembly

The latch and pin are installed and checked for correct operation.

8. Surface Treatment

Painting, powder coating or other specified finishing can be applied.

9. Load Testing

Proof load testing can be carried out according to the applicable specification.

10. Final Inspection

Dimensions, appearance, markings and latch operation are checked before packaging.

Safety Considerations

Before using an eye slip hook:

• Check the WLL marking.
• Inspect the hook body for cracks or deformation.
• Check for excessive wear.
• Inspect the safety latch.
• Ensure the load is seated correctly in the hook bowl.
• Do not load the hook on its tip.
• Do not side-load the hook unless specifically designed for it.
• Do not exceed the rated WLL.
• Avoid shock loading.
• Match the hook with compatible chain and rigging components.
• Inspect the complete lifting assembly before operation.
• Follow applicable lifting regulations and manufacturer's instructions.

The safety latch is a retaining device and should not be used as a load-bearing component.
